This detailed
view of downtown Dallas focuses on Love Airport (center), once the primary
airport for the Dallas-Fort Worth metropolis. Steady population growth
has occurred in this region since the 1970s, in large part because of
migration from other parts of the United States. The growth in this area
has partially been a function of oil, technology, and finance industries
that have flourished and made the metropolis a leading center in the southwest.
Today it maintains a population of more than 1.5 million. This growth
has required the expansion of various infrastructures, such as roads,
reservoirs, and airports (Dallas-Fort Worth International Airport is now
the principal airport). In addition, it has spawned the continued building
of new residential communities.

In this
photograph, two reservoirs are visible: one above Love Airport and one
near the bottom of the scene. The bright linear patterns are roads, and
the gray areas adjacent to them are residential developments. Isolated
bright spots are likely large businesses or concentrations of smaller
ones. The fact that there is still a significant amount of farmland and
undeveloped land (dark green) in this scene suggests there is room for
growth in this metropolis.
